Answer:
5 hours
Step-by-step explanation:
The total cost is the fee plus the hours* hourly cost
450 = 200+50*h where h is the hours
Subtract 200 from each side
450-200 = 200-200 +50h
250 = 50h
Divide each side by 50
250/50 = 50h/50
5 = h
5 hours
The inequality of it is x greater than or equal too 5
Percent means parts out of 100
x/100=x%
4/5=x%
4/5=x/100
times 100 oth sides
400/5=x
80=x
80% do
100-do=do not have
100-80=20
answer is 20%
2/9 x - 3(x - 5/4) = 2.25 - 3 7/9 x
2/9 x - 3x + 15/4 = 2.25 - 34/9 x
-25/9 x + 34/9 x = 2.25 - 15/4
x = -1.5
x = -3/2
